From the minute he came into the arena it was obvious that Konrad Bukowiecki meant business. With Polish fans roaring him on it didn't take long for him to sew up the gold medal - his opening effort spinning out to 22.46m, a new Championship Record.
But that was simply a taste of what was to come in round 3, a new World Junior or under-20 Record of 23.34m, eclipsing Jacko Gill's mark of 23.00m. To see Buko's elation at achieving such a distance AND at the premier meeting for his age group, was something to relish!
There was also a fantastic race witnessed in the final event of the first day of competition, the men's 10000m. Three youngsters from the Rift Valley of Africa staged a tremendously tactical battle for just over 24 laps of the track, before lighting the "after-burners" and sprinting the final 250m. It resulted in a win for Kenya's Rodgers Kwemoi, followed closely by Aron Kifle ERI and the 15-year-old prodigy Jacob Kiplimo UGA - they were separated by just 1.45secs!
